TIRE FOR WHEELS- Specification of Letters Patent.

Patented Nov. 6, 1906.

Application filed November 25,1905. swarm. 289,069.

To all tvhom it may concern: Be it known that I, REGINALD B. CALCUTT, acitizen of the United States, and a resident of Chicago, Cook county,Illinois, have invented certain'new and useful Improvements in Tires forWheels, of which the folriages, toy carts, velocipedes, &c., requiringvconstruction.

lowing is a full, clear, and exact description.

The object of my invention is to provide a simple yet valuableimprovement in tires for wheels,.and particularly wheels forbaby-carresiliency and at the same time economy of This I accomplish bythe means hereinafter fully described, and as particularly pointed outin the claims.

In the drawings, Figure 1 is a side View of a wheel having my inventionapplied thereto. Fig. 2 is a similar view showing the position of myimproved tire when about to be snapped or sprung onto the rim of thewheel. Fig. 3

is a perspective view of one end of said tire,

drawn to a larger scale. Fig. 4 is a perspective view of both ends ofsaid tire in position 1 ready to be coupled, drawn to a larger scale.Fig. 5 is a similar view showing said-ends coupled. Fig. 6 is aperspective view of the coupling. Fig. 7 shows cross-sections of agroup' of difl'erently-constructed coils. Fig. 8 shows a group ofcross-sections of wire of the coils of exaggerated gage.

Referring to the drawings, A represents a skeleton wheel, such ascommonly used for baby-carriages, toy carts, velocipedes, The rim B ofthis wheel is concave, and seated therein is a coiled-wire tire C, ofsuitable diameter and of sufficient length so that when its ends are.connected it will be slightly stretched or elongated, and thereby heldsecurely in its seat.

In order to secure the ends of the coiled- 'wire tire together, I preferto employ a smooth cylindrical coupling D, which is preferably about aninch or an inch and one-half long for tires for the smaller class ofwheels.

Thiscoupling is of the same or slightly greater diameter as the bore ofthe coil-wire tire and is first inserted about half its length in oneend of the tire and then when the two ends are brought together isinserted in the bore of the opposite end.- 'When the endless tire isstretched, as shown in Fig. 2 of the drawings, into its concaved seat inthe rim of thewheel, the constriction of the coll-wire t1re upon thecoupling is so great that the ends of the tire securely clamp and areheld together by the coupling.

whose channeled circumference is other-wise.

than concaved, substantially as shown in Fig. 8 of the drawings.

The coiled-wire tires may be coated, if dcsired, with any suitablematerial to prevent rusting, and it will be noticed that thecoupling'itself may be either solid or tubular.

It is obvious that while I have hereinbefore described my invention asmore suitable for the wheels of small vehicles, it may be used for tiresof large wheels for heavier vehicles. In such an event the gage of thewire would necessarily be greater, and the means for connecting the endsof the coils 'be adequate to withstand the greater strain to which thetire would be put. It will be understood that the -resiliency of thetires and the tenacity with which they retain their seats in the concaveor channel of the rim depends upon the extent to which the coiled wireis stretched and the coils are opened or separated from each other, aswell as upon the quality of wire employed.

What I claim as how is A tire for wheels comprising a suitable length ofcoiled wire bent into a circle to ,bring its'ends' together and africtionally-re tained' coupling made of one piece of metal insertedpartly in the bore of one end of said coiled wire and partly in the boreof theother to secure said ends together.

2. A tire for wheels consisting of coiled Wire the outer circumferenceof which constitutos the tread of the wheel; and a frictionally-retainedcylindrical coupling made of one piece of metal and inserted partly inthe bore of one end of said coiled wire and partly in the bore of theother to secure said ends together.

3. A tire for wheels consisting of coiled wire the outer circumferenceof whichconstitutes the tread of the wheel, and a friction-.

ally-retained coupling made of one iece of metal having a smoothunbroken sur ace and inserted partly in the bore of oneend of saidcoiled wire and partly in the bore of the other to secure said endstogether.

4. A tire for wheels consisting of coiled wire the outer circumferenceof which constitutes the tread of the Wheel, and a fritionally-retainedcylindrical coupling made of one iece of metal having a smooth unbroken'sur Zane and inserted partly in the bore of one end of said coiled Wireand partly in the bore of the other to secure said ends together.

5. A tire for wheels consisting of stretched coiled wire the outercircumference of which constitutes the tread of the Wheel, and africtionally-retained coupling made of one piece of metal having asmooth unbroken surface and inserted partly in the bore of one end ofsaid coiled Wire and partly in the bore of the other to secure said endstogether.
